Definitions
- the field of this invention relates to equipment and methods for deploying remotely- operated vehicles (ROV) subsea.
- ROV remotely- operated vehicles
- ROVs are used for access to a site and for completion a variety of different tasks.
- ROVs are generally self- propelled for proper positioning, and include manipulation linkages to allow such activities as turning valves to be accomplished by the ROV.
- the ROV typically also has video equipment and lighting to allow personnel at the surface to better direct its movements for proper positioning to accomplish a specific job.
- ROVs are frequently deployed using structures known as tether management systems (TMS).
- TMS tether management systems
- a deployed tether management system can be either a cage type w ⁇ th the ROV stored inside it or a top hat type with the ROV stored below it.
- TMS with ROV is lowered from a vessel at the surface with a winch system.
- the ROV is actuated to disengage from the TMS, and is thereafter directed to the work site location.
- the ROV is tethered to the TMS to facilitate its operation by the transmission of power and signals to the ROV from the surface through the TMS.
- One of the problems in deploying ROVs is the space required on the surface vessel to house the TMS and ROV.
- a surface vessel will include a single ROV with a TMS to accomplish a particular task. If mechanical or other difficulties ensue with regard to the ROV, there can be significant delays before a replacement unit can be brought to the surface vessel. A replacement unit would also require additional deck space.
- ROVs accomplish a variety of different functions.
- the purpose of the ROV is really to illuminate and transmit video to the surface for monitoring of particular subsea equipment or condition. It is therefore one of the objects of the present invention to allow the ability to perform certain tasks which require an ROV, even if the main ROV on the surface vessel experiences operational difficulties.
- This objective of the present invention is resolved by configuring a TMS to not only accept a main ROV, but also a smaller mini ROV, preferably housed directly below the cage type TMS or housed within the top hat type TMS. Accordingly, if problems ensue with the main ROV, certain functions can continue to be accomplished with the mini ROV until a replacement ROV is delivered to the surface vessel.
- the mini ROV can have some or most, if not all, the capabilities of the original ROV. Practically, in most applications, the mini ROV will have substantially fewer capabilities than the principal or main ROV.
- a TMS, cage type or top hat type incorporates a deployment frame and is operated by a winch from a surface vessel delivers a main ROV and a smaller mini ROV.
- the main ROV is fully functional to accomplish the necessary task subsea. However, in the event there is an operational failure of the main ROV, the mini ROV can be deployed.
- the mini ROV may have fewer functionalities than the main ROV, but can at least offer video and lighting to allow monitoring of a particular location subsea. All the necessary positioning capabilities are available on the mini ROV. DETAILED DESCRIPTION OF THE DRAWINGS
- Fig. 1 is an elevational view of the TMS, in this instance the cage type, showing the main and mini ROVs in a stacked relationship inside a deployment frame;
- FIG. 2 is a perspective view of the lower portion of the deployment frame shown in Fig. 1 adjacent the ROV;
- Fig. 3 is perspective view of the mini ROV;
- Fig. 4 is a top view of the mini ROV; and Fig. 5 is an end view of the mini ROV.
- Fig. 6 is an elevational view of the top hat type TMS showing the relationship of the main and mini ROVs with respect to a deployment frame.
- Fig. 7 is an elevational view of an additional embodiment of the invention.
- This invention is designed to operate with a "deployment frame" which is a support structure. It can internally support a main ROV 16 and a mini ROV 26 in which case it is also known as a cage. It can also be a part of a tether management system (TMS) which in a top hat format supports the main ROV 16 from within or underneath while the mini ROV 26 is supported from within.
- TMS tether management system
- the cage type TMS comprises a deployment frame 10 is initially supported on a surface vessel (not shown) and is connected a boom on such vessel so that it can be swung overboard.
- a cable attached to a bullet 12 at the top of deployment frame 10 allows for raising and lowering of the deployment frame 10.
- the main ROV 16 is a design well known in the art. It typically has a plurality of thrusters 18 as well as manipulators 20. The position of the TMS can also be controlled with thrusters 22 if the TMS is powered; some TMS types have no thrusters attached.
- the deployment frame 10 has an open end adjacent the manipulators 20 to allow the main ROV 16 to emerge from the deployment frame 10.
- Deployment frame 10 also includes a transformer 24, integrated into the ROV 16.
- a winch 28 is mounted in the deployment frame 10 that allows the mini ROV 26 to be retrieved by its tether.
- the winch 28 is a tether management system that pays out or takes up the tether to facilitate ROV movements.
- the cable extends over a pulley 30 which is partially hidden in Fig. 2 and disposed between the winch 28 and the electronics bottle 32.
- a bladder 34 and a transformer 36 Adjacent the transformer 36 is a valve pack 38.
- a subframe 40 stabilizes the mini ROV 26 in deployment frame 10.
- the mini ROV 26 itself has a frame 42 and a plurality of thrusters 44 so that it can be properly positioned.
- the thrusters are illustrated in Fig. 5.
- the front of the mini ROV 26 is shown in Fig. 3. It has lights 46 and a camera 48 shown in Fig. 4.
- Fig. 5 illustrates the electronic bottles 50 which house, among other things, telemetry equipment. Adjacent the lights 46 is a pan/tilt control device 52.
- Those skilled in the art will appreciate that the configuration of the mini ROV 26 can be changed without departing from the spirit of the invention. Although shown below the main ROV 16 to accommodate a retrofit to an existing cage, the mini ROV 26 can be placed above the much heavier main ROV 16 to add greater stability to the cage.
- mini ROV 26 can be incorporated in the mini ROV 26 without departing from the spirit of the invention.
- a plurality of mini ROVs can also be deployed.
- the mini ROV 26 could potentially have manipulators for inserting or removing stabs or operating valves.
- the capabilities of the mini ROV are more limited to allowing observation using the lights 46 and the camera 48.
- certain operations subsea only require monitoring. Accordingly such monitoring activities can continue while a replacement ROV is delivered to the surface vessel, or during the time that repairs are made to the ROV on the surface vessel or at a remote location.
- the mini ROV 26 can be used in rescue operations of the main ROV 16, or they can complete certain tasks together. For example, while landing a "Christmas tree" or a blow- out preventer, the main ROV 16 and the mini-ROV 20 can operate together. If the tether on the main ROV 16 is tangled, the mini ROV 26 can grapple it and untangle it. The mini ROV 26 can also apply a hook to the main ROV 16 to aid in rescue efforts from the vessel at the surface. The mini ROV 26 can also take corrosion readings on pipes or vessels.
- a deployment frame 10 having the same footprint can now accommodate a reserve backup unit or multiple units which can allow certain operations to continue while the main ROV 16 is replaced or repaired.
- FIG. 6 An alternative embodiment is shown in Figure 6.
- This is the top hat arrangement which includes a tether management system 60 supported in a deployment frame 62.
- the main ROV 64 is suspended from the lower end 66 of the deployment frame 62.
- the mini ROV 68 is disposed within the deployment frame 62 and has its own tether management system 70.
- the deployment frame 62 is supported from the surface vessel by a support cable 72.
- thrusters can be employed with the deployment frame 62 for positioning subsea.
- both the main ROV 16 and the mini ROV 26 are mounted within the deployment frame 10.
- the main ROV 64 is suspended below the deployment frame 62 while the mini ROV 68 is housed within the deployment frame 62.
- FIG. 7 shows a further alternative embodiment in which the tether management system 60' is supported in a deployment frame 62'.
- the main ROV 64' is suspended from the lower end 66' of the deployment frame 62'.
- the mini ROV 68' is also disposed underneath the deployment frame 62' and has its own tether management system 70'.
- the deployment frame 62' is supported from the surface vessel by a support cable 72'.
- thrusters can be employed with the deployment frame 62' for positioning subsea.
- the main ROV 64' and the mini ROV 68' are housed side by side, under the deployment frame 62'.
